Fabrication of flexible superhydrophobic biomimic surfaces

Flexible superhydrophobic films are fabricated by thermally evaporating silver nanoparticles (Ag NPs) on the created flexible hemispheres arrays and modifying the Ag NPs surface with 1-dodecanethiol. The morphology of the generated biomimic film is similar to natural lotus leaves consisting of hierarchical micro/nano structures. The biomimic film exhibits remarkable superhydrophobicity with a high water contact angle (CA) of about 166 degrees and a low sliding angle (SA) of less than 3 degrees.
